Some JPT plugs have pin numbers on the casing.

I made contact with the coil supplier yesterday to see if they could help. They could not but did agree to contact the manufacturer . I suppose my other option is to see if I can track down an original with its loom so that I can identify the pin configuration via the wiring colours/ numbers
I've got a factory XU10J4 manual. I'll run it through the scanner tomorrow.

Hope this helps.

Thanks for the diagram Peter, but from the looks of it, those coils are the later two wire ones with an earth via the coil core as they are bolted down, whereas the early type had no bolt fixing. Welshpug has posted a load of circuit diagrams for various cars elsewhere on the site that B1ack-Mi16 refers to above which have been/ are helpful. Beginning to think that I should have stuck with a coil pack and wasted spark, but this route is much more elegant as long as I have correctly assumed that the trigger transistors are in the coils so that the ecu supplies the pulse on pin 3 to disconnect the primary current .

look at the plug above, pin 1 is on the right looking at the coil, left looking at the front of the plug.

They are all numbered the same and they are keyed so they can only go on one way round. Use the pin numbers on the plug I posted a photo of.

I'm 100% confident.
